This paper endogenises the extent of intra-sectoral competition in a multi-sectoral model of oligopoly in general equilibrium. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand behaviour,...

Almost twenty-five years after the appearance of Dixit and Stiglitz’s paper on monopolistic competition and optimum product diversity, I try to take stock of the progress which has been made in applying their approach to international trade theory. I review the principal applications to trade...

A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital market liberalisation. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under...

I explore the interactions between comparative, competitive and absolute advantage in a two-country model of oligopoly in general equilibrium. Comparative advantage always determines the direction of trade, but both competitive and absolute advantage affect resource allocation, trade patterns...

Typically, a small and open economy trades goods at given world prices. Here, we present a model of a very open small economy, where capital and labor are internationally mobile, too. When investing into infrastructure, the economy’s government attracts not only mobile capital but mobile...

Typically, a small and open economy trades goods at given worl prices. Here, we present a model of a very open small economy, where capital and labor are internationally mobile, too. When targeting mobile capital ("FDI"), the economy's government attracts not only mobile capital but mobile...

I argue that increased foreign competition can affect technical choice and skill differentials even when actual imports do not rise significantly. I present a model of General Oligopolistic Equilibrium ("GOLE") in which a reduction in import barriers (whether technological or policy-imposed)...

I outline the effect of business networks on trade, FDI and wel- fare in a two-country, two-firm duopoly. The network effect, following Greaney (2002), is modelled as a marginal cost disadvantage facing a firm from Foreign in selling to Home. Unlike traditional trade costs, this cost cannot be...

This paper studies the strategic behavior of multinationals towards weak labor standards in developing countries (South). Without a marginal cost pricing policy, abundant labor in the South gives firms the power to set wages through their choice of output. A strategic reduction in output offsets...

Until recently, government procurement bidding processes have generally favored domestic firms by awarding the contract to a domestic firm even if a foreign firm tenders a lower bid, so long as the difference between the two is sufficiently small. This has been replaced by an agreement...
